Bear Ecology
May live 15–30 years. Grizzly bears are generally 1.5 to 2 times larger than black bears of the same sex and age class within the same geographic region, and they have longer, more curved claws. Lifetime home range: male, 800–2,000 square miles, female, 300–550 square miles. Agile; can run up to 40 mph.
A greater yellowstone ecosystem grizzly bear case study
The nal USFWS decision to delist the GYE grizzly bear on April 30, 2007, and again on July 31, 2017, was based primarily on demographic population data; however, genetics data were also taken into account. For more information about the study area, US grizzly bear distribution and population sta-tus, and ESA history, see Part I of the case study.
